Case Adds Two New D Series Excavators
Two crawler excavators from CASE – the CX130D and CX160D – provide faster cycle times and feature powerful hydraulics and greater fuel efficiency, the company says. The new models are designed to provide up to 5 percent faster cycle times, have improved responsiveness and multifunctional controls, and up to 8 percent greater fuel efficiency.

The CX130D and CX160D’s new electronically controlled hydraulic pump and larger control and solenoid valves boost breakout forces, increase lifting strength and improve responsiveness. Each model also offers more standard features than previous CASE excavators, simplifying the buying process and making them extremely versatile and operator friendly. (For a video walk-around, click on the image.)
The CX130D and CX160D employ an SCR Tier 4 Final solution that provides up to 8 percent greater fuel efficiency without sacrificing power. SCR lets the engine run at peak performance throughout the work cycle and, because it works without a diesel particulate filter (DPF), there’s no DPF regeneration or associated lifetime service costs. This helps maximize uptime and performance – all with minimal maintenance.
Faster cycle times are achieved through a new electronically controlled pump, a larger control valve and multiple sensors. These features combine with the CASE Intelligent Hydraulic System and its four integrated control systems to make the best use of the machine’s hydraulic power and momentum, resulting in added strength and fuel efficiency.
The four systems that make up the CASE Intelligent Hydraulic System are: Boom Economy Control (BEC), which reduces RPMs by using gravity during boom down and swing; Auto Economy Control (AEC), which lowers RPMs during idle and automatically shuts down the engine after a preset idle time; Swing Relief Control (SWC), which reduces hydraulic power at the swing start; and Spool Stroke Control (SSC), which adjusts hydraulic pressure during digs.
Using improvements to the Spool Stroke Control system, the CX130D and CX160D excavators re-use hydraulic fluid whenever possible to automatically increase cycle times and efficiency.
The arm and boom of each new excavator have been built stronger for greater durability and to support the added power of the machine. The undercarriage is built with thicker steel and a new single-slope design that reduces dirt accumulation and eases cleaning. The CX130D is also available with an optional front dozer blade that provides added stability, as well as grading and backfilling capabilities.
Each machine is available with a new (optional) LED working light package that provides illumination similar to sunlight – and more than three-times brighter than halogen – allowing contractors to work around the clock.
